In India, Vatsyayan's Kama Sutra, the oldest text on sex, says that if you make real wild love, once a year is enough! To modern man, this seems almost impossible - once a year? Vatsyayan is the first sexologist in the world and the first to bring meditation to sex; the first to come to understand its deepest centers. And he's right. If it's really about the maximum, once is almost enough. It will satisfy you so deeply that the afterglow will last for months.
